Non-human papilloma virus associated adenocarcinomas of the cervix uteri. Cytologic features and diagnostic agreement using whole slide digital cytology imaging.

BACKGROUND: Non-Human Papilloma Virus associated adenocarcinomas (NHPVAs) are uncommon tumors of the cervix uteri which often show a deceptive morphology. Therefore, their diagnostic assessment may be challenging. Slide digital cytology imaging may be an useful tool to improve cytological diagnostic accuracy. However, this novel technology has not been applied to NHPVAs associated cytologies yet. METHODS: The study included 31 whole slide digital cytology cases from 10 women with a proven histological diagnosis of NHPVA. As a control group, three further digital slides, from two women with a histological diagnosis of squamous intraepithelial lesion (SIL), were included. The digitally scanned cytological slides were revised to assess the concordance rate among three observers and to find out the most relevant NHPVA cytological criteria. RESULTS: Overall diagnostic agreement between observers was 67.60% (K = 0.50; P < 0.0001). At the consensus diagnosis 34 cases were re-classified as at least suspicious for glandular lesion (n = 24), SIL (n = 2) and negative (n = 8). The most relevant cytologic features for atypical glandular cells or adenocarcinoma at consensus were evident nucleoli, nuclear overlapping and atypical enlarged nuclei. CONCLUSIONS: The diagnosis of NHPVA in digital cytology is feasible using criteria which are also used in conventional microscopy. Our study shows a moderate agreement for the cytological diagnosis of NHPVAs using whole slide digital cytology approach. These results are discussed taking into account the most relevant differential diagnostic issues.

Cytopathology practice during the COVID-19 postlockdown: An Italian experience.

BACKGROUND: During the current coronavirus disease 2019 (COVID-19) pandemic, the cytopathology workload has decreased remarkably worldwide as all screening and elective procedures have been postponed to prioritize the clinical management of patients at high oncological risk. In the current study, the authors provide data on the lasting impact of COVID-19 on cytopathology practice during the initial phases of the Italian postlockdown period. METHODS: The percentages of the cytological sample types processed at the University of Naples Federico II during the first 12 weeks of the Italian postlockdown period were compared with those of the same period in 2019. The study period was divided into four 3-week periods. Differences in the rates of malignant diagnoses were also assessed. RESULTS: During the 12-week study period, the overall cytological sample workload decreased by 41.6% in comparison with 2019. In particular, the workload significantly declined for each sample type: Pap smears, -33.3%; urine, -42.8%; serous fluids, -14.4%; thyroid, -54.5%; breast, -43%; lymph node, -27.3%; and salivary gland, -61%. By contrast, the overall malignancy rate was significantly increased (P = .0011). CONCLUSIONS: The reduction in the cytological sample workload during the postlockdown period still represents an ongoing effect of the COVID-19 pandemic. On the other hand, the rise in the overall malignancy rate reflects the importance of prioritizing diagnostic procedures for patients at high oncological risk.

Primary High-Grade Angiosarcoma of the Breast in a Young Woman With Breast Implants: A Rare Case and a Review of Literature.

Primary angiosarcoma (AS) of the breast is an extremely unusual variant of breast malignancies, and its incidence is about 0.05% of all primary breast tumors. In this article, we present a rare case of a primary AS that developed in a young woman with breast implants. This case report emphasizes importance of early investigation for accurate diagnosis and proper management of the breast AS, along with a correlation of histopathologic, radiologic, and clinical findings.

Global impact of the COVID-19 pandemic on cytopathology practice: Results from an international survey of laboratories in 23 countries.

BACKGROUND: To the authors' knowledge, the impact of the coronavirus disease 2019 (COVID-19) pandemic on cytopathology practices worldwide has not been investigated formally. In the current study, data from 41 respondents from 23 countries were reported. METHODS: Data regarding the activity of each cytopathology laboratory during 4 weeks of COVID-19 lockdown were collected and compared with those obtained during the corresponding period in 2019. The overall number and percentage of exfoliative and fine-needle aspiration cytology samples from each anatomic site were recorded. Differences in the malignancy and suspicious rates between the 2 periods were analyzed using a meta-analytical approach. RESULTS: Overall, the sample volume was lower compared with 2019 (104,319 samples vs 190,225 samples), with an average volume reduction of 45.3% (range, 0.1%-98.0%). The percentage of samples from the cervicovaginal tract, thyroid, and anorectal region was significantly reduced (P < .05). Conversely, the percentage of samples from the urinary tract, serous cavities, breast, lymph nodes, respiratory tract, salivary glands, central nervous system, gastrointestinal tract, pancreas, liver, and biliary tract increased (P < .05). An overall increase of 5.56% (95% CI, 3.77%-7.35%) in the malignancy rate in nongynecological samples during the COVID-19 pandemic was observed. When the suspicious category was included, the overall increase was 6.95% (95% CI, 4.63%-9.27%). CONCLUSIONS: The COVID-19 pandemic resulted in a drastic reduction in the total number of cytology specimens regardless of anatomic site or specimen type. The rate of malignancy increased, reflecting the prioritization of patients with cancer who were considered to be at high risk. Prospective monitoring of the effect of delays in access to health services during the lockdown period is warranted.
